Slippery Elm Inner Bark (Ulmus fulva). Its principle ingredient is mucilage, a polysaccharide similar to that in flaxseed. Slippery Elm is a demulcent and emollient and can be applied as a poultice to all wounds or ulcers to good effect. Internally it is used for stomach and intestinal ulcers. The primary use of slippery elm is for the GI tract where it can provide nutrition, and a soothing coating over stomach and colon, while easing intestinal ulcers. It is taken either orally or as a bolus (used as a suppository) or added to enemas. It can neutralize stomach acidity and absorb foul gases and it helps in the digestion of dairy products.
